OpenClaw v2026.4.27 — Docker GPU, Proxy, DeepInfra & Security Hardening

Released: April 29, 2026 at 22:12 UTC
Source: GitHub Release

OpenClaw shipped another significant daily release — its fourth stable release in five days. v2026.4.27 brings infrastructure maturity, a major new provider, channel expansions, and extensive security hardening.

Key additions:

Docker GPU Passthrough — Opt-in sandbox.docker.gpus enables local GPU workloads inside sandboxed agents when the host runtime supports --gpus.
Outbound Proxy — Operator-managed proxy routing via proxy.enabled + proxy.proxyUrl with strict http:// forward-proxy validation, loopback-only Gateway bypass, and dispatcher cleanup on exit.
Gateway Cold-Start Optimizations — Channels start without blocking on primary-model prewarm; plugins.enabled=false skips auto-discovery and runtime-deps staging; lightweight runtimeContexts for bundled channels; startup trace timings and max-RSS reporting.
DeepInfra Provider — New bundled provider with DEEPINFRA_API_KEY onboarding, dynamic OpenAI-compatible model discovery, image generation/editing, media understanding, TTS, text-to-video, memory embeddings, and provider-owned base URL policy.
Codex Computer Use — New /codex computer-use status/install CLI commands, marketplace discovery, fail-closed MCP server checks, and local bundling of Codex/Claude adapters via ACPX runtime (eliminates live npx resolution dependency).
Tencent Yuanbao — New external channel plugin (openclaw-plugin-yuanbao) with quick-start docs.
QQBot Overhaul — Full group chat support (history, @-mention gating, activation modes, per-group config, FIFO queue), C2C stream_messages with StreamingController, unified sendMedia with chunked upload.
Discord Privacy-by-Default — Group/channel replies are now private by default unless the agent explicitly uses the message tool. Legacy auto-posting restored via messages.groupChat.visibleReplies: "automatic".
Telegram Improvements — Multi-bot approval routing, sticky Bot API fallbacks, setWebhook retry, immediate typing cues, --thread-id support for cron jobs.
Plugin SDK Refactor — Explicit activation.onStartup metadata, manifest-driven model catalogs (modelCatalog.aliases/suppressions), provider catalogs moved into plugin manifests, new test/helper SDK subpaths, legacy compatibility exports restored.
Security Hardening — Control UI redaction of tool-call args and secrets; session redaction persistence; console sink token redaction (sk-*, Bearer values); trusted proxy loopback controls; device auth stale-token cleanup; macOS LaunchAgent owner-only env file loading; legacy CLAWDBOT_*/MOLTBOT_* env var warnings.

Mistral Medium 3.5, Vibe Remote Agents & Work Mode in Le Chat

Announced: April 29, 2026
Source: Mistral AI Blog

Mistral AI launched a triple announcement that positions it as a serious competitor in both frontier models and agentic coding.

Mistral Medium 3.5:

Dense 128B model with 256k context window
Merges instruction-following, reasoning, and coding into a single set of weights
Released as open weights under a modified MIT license
Runs on as few as four GPUs (Q4 with ~70GB VRAM)
77.6% on SWE-Bench Verified — ahead of Devstral 2 and Qwen3.5 397B A17B
Becomes the default model in Le Chat and replaces Devstral 2 in Vibe CLI
API pricing: $1.5/M input tokens, $7.5/M output tokens
NVIDIA partnership for prototyping on build.nvidia.com and NIM containerized inference

Vibe Remote Agents:

Cloud-based coding agents that run asynchronously, in parallel, and notify you when finished
Spawn from Vibe CLI or Le Chat; teleport local sessions to cloud with history preservation
Real-time visibility into file diffs, tool calls, progress states
Isolated sandboxed execution; auto-open GitHub PRs on completion
Integrations: GitHub, Linear, Jira, Sentry, Slack, Teams

Work Mode in Le Chat (Preview):

Agentic harness for complex multi-step tasks powered by Medium 3.5
Cross-tool workflows (email, calendar, messages), research/synthesis, action automation
Connectors are on by default; explicit approval before sensitive actions

Warp Terminal Goes Open-Source Under AGPL

Date: April 28, 2026
Source: Warp Blog

The AI-native terminal (nearly 1 million active developers) open-sourced its client under AGPL. Key details:

Repository: github.com/warpdotdev/warp
Agent-first workflow: Development powered by Oz (Warp's cloud agent orchestration) and OpenAI GPT models
OpenAI is the founding sponsor of the repository
New model support: Kimi, MiniMax, Qwen, plus "auto (open)" router
Customizable experience from minimal terminal to full agentic development environment (ADE)
Public GitHub issues are now the source of truth for feature tracking

"Humans managing agents at scale to build production-grade software is the model, and implementing this model in the open will allow software to improve most quickly." — Zach Lloyd, Warp founder

OpenAI Brings GPT-5.5, Codex & Managed Agents to AWS

Date: April 28, 2026
Sources: OpenAI Blog, The Register

OpenAI and AWS expanded their strategic partnership with three capabilities in limited preview:

OpenAI models on Amazon Bedrock — GPT-5.5 and GPT-5.4 available within existing AWS security, identity, and procurement workflows
Codex on AWS — Organizations can power Codex with OpenAI models served directly from Bedrock; customer data processed by Amazon Bedrock; eligible customers can apply Codex usage toward AWS cloud commitments
Amazon Bedrock Managed Agents, powered by OpenAI — Enterprise agent deployment framework with AWS security/compliance controls, handling orchestration, tool use, and governance

Strategic signal: This announcement came one day after the Microsoft-OpenAI exclusivity rewrite, demonstrating OpenAI's immediate diversification across cloud providers.

Claude Code Security Advisories

Date: April 28–29, 2026
Sources: GitHub Advisory GHSA-jh7p-qr78-84p7, GitHub Advisory GHSA-mhg7-666j-cqg4

Two security advisories were published for Claude Code:

CVE-2026-21852 / GHSA-jh7p-qr78-84p7 — Moderate severity (5.3/10). Attacker-controlled repositories could exfiltrate Anthropic API keys before trust confirmation by overriding ANTHROPIC_BASE_URL in repository settings. Patched in v2.0.65.
GHSA-mhg7-666j-cqg4 — Command injection vulnerability via piped sed operations with echo, allowing attackers to bypass file write protections.
